Can't believe I managed it! Feel so great now! Found the second 5 minute run pretty tough, but boy did I feel good when it was finished. No problem with my breathing now, I think it was a combination of cold air and not enough puffs on my asthma reliever last week. I managed to control my breathing like Laura said, and only breathed in through my nose!! Can't wait for my next run, planned for bank holiday Monday. It is in an unfamiliar town but I have plotted out my route already using walk jog run and am so excited! My 15 year old daughter is planning on joining me which is a bit daunting; she can't understand why my "runs" are "only jogs and not sprints"!!!! Oh to be so young again!!! Best of luck to all who are also on W4!
